IMPRQVEMENT 1N HAND CORN-PLANTER.

The Schedule referred t in these Letters Patent and making part of the same To all ywhomy it may concern:

Be it kndivn that I, HUGH DYER, of Fort Scott, in the county of Bourbon and State of Kansas, have invented a new and useful Improvement in Hand Corn-Planter; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in tlie art to make and use the same, reference being had to the accompanying drawing forming part of this specitication.

Figure 1 is a. detail longitudinal section of my imgrowloed hand corn-planter, taken through the line x x,

Figure 2 is adetail longitudinal section of the same, taken through the line y y, fig. 1.

Figure 3 is a detail cross-section of the same, taken through the line z z, iig. l.

Similar letters of reference indicate corresponding parts. v

My invention relates to hand corn-planters, and consists in certain improvements which will first beV described in connection with all that is necessary to a clear understanding thereof, and then clearly specilied in-the summary or claim. I

A is the body or case ot' the machine, which'is made of light sheet inet-al, galvanized, or otherwise secured from rusting. drical in form, and of convenient size and length.

In the side of the upper part ot' the body A is formed an opening,for convenience in putting in .the seed, which opening lis closed with a sliding door, a.

The upper end of the` .body A is closed by a disk, B, iitted into it, and secured by screws passing into its edge through holes in the said body A.

In the lower end of the body-A are secured two disks, C D, at such a distance apart as to allow the dropping disk E to be placed between them.

Two holes for lthe passage of the seed are formed iu each of the disks C D, and the disks are so arranged that the said holes will not be directly over each other, as shown in iig. 3.

' In the oscillating or dropping-diskll are formed two holes, corresllonding in position with the holes in the two disks, O D, so that the said holes, which are of such a size as to contain enough seed to form a hill, may receive seed from the holes in the upper disk, C, aud convey it to the holes in the lower disk, I), through which it drops into the.lowe1' part of the machine,

The lower side of the diskO, in front of the holes through it, is recessed, and in the recesses thus formed are placed pieces of sponge, or other elastic and yielding material, toprevent any more seed than enough to fill the holes in the disk E from being carried out by thc said disk, and also to prevent the seed from The body A is made cyliu .being injured by being carried beneath the said disk vThe oscillating disk E may be adjusted in size as required by'the gaugcspF, placed in them, andoperated by set-screws passing in through the said disk E, and which may be reached and operated through holes in t-he sides of the body A.

Throughthecenter of the four disks, B C D E, are formed round holes, for the passage of the plungershaft G,'which has a handle, H, secured to its upper end, and to the lower cud of which is attached the plunger I.

In the side of the part of the shaft G that moves up and down through theV three disks, G E D, is formed a spiral groove, g', making about halt` a turn around the said shaft G, and extending the length of a stroke.

The groove y' should be lined with metal, to prel vent wear; and lin it works the point of the screw J, which passes in through the edge of' the disk E, as shown in tig. 2, so that the said disk E may be oscillated to drop the seed by the lip-and-down movement of the plunger-shaft. i

To the opposite sides ot' the lower end of the body A are attached the upper ends of the plates K, which taper to, or nearly to a point at their lower ends, and the edges o'fwhich may be upon a. straight or curved line, as may-be desired. The latter I prefer, as it gives more space for the seed to drop past the plunger I. Y 4

To the lower end of the body A, between the up per ends of the plates K, are' attached the elastic plates L, which are curved to correspond with the shape ofthe edges of the plates K, and the lower ends of which meet, so as to make the lower edge ot' the planter wedge-shaped, to enable it to be readily forced into the ground.

The plunger l is a thick plate, upon the upper part-s of the end edges of which are formed projections or lugs i', which pass through and work in vert-ical slots in the middle partsot the plates K, as shown in iig, l, to guide t-he plunger I, and limit its up-and-down movement.

M is a plate or step, having a flange `formed upon its Vlower end, to serve as a gauge'or stop, to regulate the depth to which the planter enters the ground, and which is adjustably secured to the plates K by bolts passing through the plates K and M, one or the other ot' which plates is slotted, so that the gauges or stops may be adjusted to allow the planter to enter the ground more or less, as may be required.

By this construction, as the seed is dropped through the disks G D E, by then-lavement of the plungershaft` G, it falls into the lower part of the chamber' formed by the plates K Il, below the plunger I, and',

as the said plunger is 'forced down after the planter has been thrust into the ground to'tlxe required depth, the saidlseed is allowed to drop out into tbe hole in the ground, by the spring plates L being forced apart by the s aid downward movement oF the said plunger I.

Havingl thus described my invention,

claim as new and desire to secure oyLetters Patent- 1. The-.combination of the oscillating disk E and adjustable gauges F, arranged between the disks O D, as and for the purpose described.

2. The combination of disk E with screw/'J and spirally-cbanueled sl1af`tG,as and for the purpose de- HUGH DYER.
